Smoke generator with deflector

Abstract

A smoke generator for anti-burglar purposes includes a canister holding means for holding a canister for chemicals to be used to generate smoke wherein the smoke generator further includes a smoke deflector arranged below the position of the canister for even distribution of generated smoke, and wherein the smoke deflector have a smoke deflector cavity of sector shape. The smoke generator is provided with a cartridge for the canister to ease replacement of used or expired canister. The smoke deflector is provided with a residual collector to prevent residuals and debris from littering the room where the smoke generator is used.

What is claimed is: 
     
         1 . A smoke generator having a body housing electronics and a battery power source, the body being arranged to co-operate with a replaceable canister of chemicals that is arranged to generate smoke under the control of the electronics, the canister being housed in a canister housing allowing a user to handle the housing without directly contacting the canister and ensuring separation of the electronics from the smoke generating chemistry, the body and replaceable canister housing being arranged to be releasably connected together and adapted such that the act of connecting them establishes an electrical connection between the electronics and the canister of chemicals. 
     
     
         2 . The smoke generator of  claim 1 , wherein the replaceable canister is electrically triggered by application of electrical signals from the control electronics, the canister having electrical contact areas for the application of said electrical signals. 
     
     
         3 . The smoke generator of  claim 1 , wherein the electronics to activate the replaceable canister are housed in a portion of the smoke generator other than the canister, and the chemical part is housed in the canister housing, the housing separating the electronics from the chemical part. 
     
     
         4 . The smoke generator of  claim 1 , wherein the body that houses the control electronics and battery power source includes a smoke outlet of the smoke generator, a smoke streaming conduit being provided between a smoke outlet of the canister and the smoke outlet of the smoke generator. 
     
     
         5 . The smoke generator of  claim 1 , further comprising a smoke deflector. 
     
     
         6 . The smoke generator of  claim 1 , wherein the smoke deflector is arranged in a smoke streaming path between the smoke outlet of the canister and a smoke outlet of the smoke generator, the smoke deflector being configured to produce even distribution of generated smoke, wherein the smoke deflector is configured to have a smoke deflector cavity of sector shape. 
     
     
         7 . The smoke generator of  claim 1 , wherein the smoke deflector is arranged below the position of the canister for even distribution of generated smoke, and wherein the smoke deflector has a smoke deflector cavity of sector shape. 
     
     
         8 . The smoke generator of  claim 1 , wherein the canister housing and the smoke generator have co-operating, releasable fastening elements to hold the canister housing and the smoke generator together and to allow them to be separated without the use of tools. 
     
     
         9 . The smoke generator of  claim 1 , wherein the canister housing is so configured that the housing prevents a user from touching a canister contained within the housing unless the housing is opened. 
     
     
         10 . The smoke generator of  claim 1 , configured for wall mounting, optionally wherein the smoke generator further comprises a wall mount by means of which the smoke generator can be mounted on a wall.
